I got the NEX-7 last week and am using it with Nikon and Leica lenses. No question that 24 mp delivers the goods. The menu system is hopeless, I'm still trying to figure it out where I can remember what is where and the squirrels that designed it should have their nuts taken away. Another great camera concept let down by the little things. I'm not certain what a firmware update could achieve to straighten the menu system out, but I have been surprised before.
I recently got my NEX 7. I became so frustrated, I sat with the camera, instruction book, for 3 or 4 hours, and made a 4"x5" card "cheat sheet" with all the very basic functions an experienced photographer would need. For Example:
1.How to Format the card
2. How to set the ISO.
3. How to set the exposure mode (i.e. Aperature preferred, shutter preferred, manual, Program).
4. If I select "Aperture Preferred" How do I set shutter speed, and F stop? (Don't laugh--took me a long time to see how to set shutter speed and F stop). Used to be a F stop ring around the lens, and shutter speed dial on top of camera. Well, Olympus had the shutter speed ring around the lens, but that was an exception!
5. Ditto for "Shutter" preferred, or manual.
6. How to set Single frame, or Multiple frame motor drive.
To me the epitome as to how to design a digital camera is the A900, and 645D, both of which are my current cameras. Both the easiest digital cameras I have ever used.
It is embarrasing, I have been involved in photography in a serious way for well over 55 years, and when a friend buys a "simple point and shoot" camera, and asks me how to use it, I have to tell them I have no clue. They look at my collection of film cameras, and when I show them one shutter speed dial, one aperature on the lens, and one dial to set ISO, they are incredulous as to how simple they are!
End of rant.
